2.4.7.1 Library Prerequisites

In addition to obtaining the project source code (see section Where to Get Crystal Space), you
may also want to download and compile several support libraries used for image
manipulation (see section External Libraries). The libraries ‘libpng’ and
‘libjpeg’, which are present on many Unix installations, are absent from
MacOS/X. The optional ‘libmng’ is less common.

Various package managers exist to simplify the task of installing command-line
tools and development libraries, such as ‘libpng’ and ‘libjpeg’.
Choose one of the package managers below and follow its documentation to
install prerequisites libraries.

Alternately, the libraries can be built manually. You can download the
required external library source code packages from their canonical download
sites (see section External Libraries). Follow the included documentation to build
and install each library.
